IMPROVEMENT-IN SPINNING-FRAMES.

Specification forming part of Letters Patent No. 189,890, dated April24, 1877 application filed October 2, 1876.

To all whom it may concern Be itknown that 1, WILLIAM E. DRAPER, of Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improved Spinning-Iirame, of which the followbobbin or yarn-load by a long bearing, as in the well known Sawyer plan, the bolster steadying the spindle near its upper end.

In another form of spinning-frame, a whirl made to revolve upon a'stud has been adapted to engage the'base of the bobbin, the upper end of which was restricted as to its movements, through a cylindrical pin or top piece projecting from the upper end of the bobbin into a cylindrical opening in a guide-board, a spindle to extend through the bobbin being dispensed with. I do not claim the devices just enumerated either separately or combined.

This my present invention, has reference to a spinning-frame having a bobbin of this latter class and moved by a whirl, and the invention consists in such a construction of this top-steadying pin, or the guide for it, or both, that will afford spaces between the contact points of the steadying pin and guide to permit the twisted or spun thread to slip about the point of the pin which forms the lip of the bobbin as the thread is wound upon the bobbin. V

In the plan referred to, and upon which this invention is considered an improvement, the top piece at the upper end of the bobbin is round, or like the point of an ordinary spindle, and-the guide-opening to receive it, also round, is enough larger than the toppiece to permit the free passage of the yarn about the top piece, and consequently the upper end of the bobbin is not efl'ectually steadied.

In this my improved plan, opposed port-ions of the top piece are at all times in contact with portions of the guide-surface, or faces surroundin the top piece, such guide-surface bounding the opening in which the toppiece revolves and by which it is held steady during the rapid rotations of the bobbin and its whirl.

' Figure 1 represents in front view, and partially in section, sufficient of a spinning-frame to illustrate my improvement. Fig. 2 is a top view of the guide-surface for the top piece; Fig. 3, a view of the top of the bobbin with the top piece'attached; Fig. 4, a modified form.

of whirl; Figs. 5 and 6,- modified forms of the guide-surface or wall; and Fig. 7, a further modification.

The frame a of the machine is provided with a lifting ring-rail, b, ring a, traveler d, and drawing-rollers e, of any ordinary construction, and they may be operated in any ordinary way. The rail f is provided with a whirl-holding stud, g, one for each whirl h, and bobbin i, the whirl being revolved upon such stud by a band, j. The bobbin, as represented in Fig. 1, is placed within the socketed upper portion of the whirl, the friction between the whirl and bobbin being sufiicient to move the bobbin with the whirl as the latter is revolved. Instead of the whirl shown in Fig. 1, I may employ any other suitable form of whirl, as in Fig. 4:, where the pins 70 engage the lower end of the bobbin in the usual manner.

At the upper end of the bobbin is placed a top piece, I, adapted to extend upward through a guide-opening in a guide-board, m. This guide-opening for the top piece I and the top piece are so constructed with relation to each other as to present bearing portions and spaces at intervals between the guide-surface or wall and the peripheral surface of the top piece.

Under the construction shown in Figs. 1, 2, 3, the top piece is grooved ate, (in this instance at four places, but it may be at two or more places,) leaving four bearing projections, 0 0, adapted to meet the acting-face of the guide-opening p at difl'erent points. The guide-opening in these figures is shown as made in a block of raw-hide, q, attached to the guide-board m, the opening being cylindrical. Between the bearing projections and the guide-opening there are four spaces shown in Fig. 2, in which the yarn, being spun and extended from the usual front roller of the drawing-rollers e to the traveler, is contained.

The yarn 'mu's'tmove-aboutwith the upper end of'the'bobbimiin this instance -it is contained between one of the openings in the top piece and the guiding-surface therefor,) and.

of the spaces between the top piece and guide-surface for thetoppiece, moves about with the bobbin. Were both the top ';'1 i"ec'e and guide circular, it would be necessary, as before described, to make an annular spacelarge enough for the ..pass'a ge of the ,yarn without injurious friction, or for the passage of such bunches upon the same as iti's wished to have pass through without'breaking down the end, and so made, the guide-opening would not act to eli'ectually steady 'the top piece, and consequently the bobbin.

By grooving the top piece, as described, the yarn is permitted to extend through one of the grooves, and move about with'thebobbin and top piece, when steadied at'the'top. As the yarn is wound upon the surface of 'th'e'bobbin, it must slip or change its position with reference to the top piece, or upper end of the bobbin, with which it is in contact. 'When the groove m, holding the yarn, comes opposite a slot, 9', the yarn, then free, moves or slips from one to another groove, skipping one or more grooves, according to'the'tension upon the yarn then being 'woun'd.

It will be seen that'a top piece and guidesnrface, constructed as described, afi'ords numerous bearing-points between the movingsurface of the top piece and the guide-opening and the top piece, and, consequently, the bobbin is effectually steadied at its upper end, thereby permitting it to be run. very rapidly with less wabbling.

The gist of this invention is the provision of several bearing -points and intermediate spaces between 101301) piece or 'upper'en'dof the spindle and the guide surface or "wall about it, whereby the bobbin is efiectn'ally steadied through contact ofthe top piece with the guide-surface at several points, the spaces permitting the yarn to turn with the top piece and bobbin without injurious friction,"and as the yarn is wound upon the bobbin'it'is'permitted to slip or change iislocation or position with relation to the top piece or'upper end of the bobbin. By the use of a rawhide guide piece, q, lubrication of the top piece is avoided.

I Instead of making the :guide-surfacebircu- 'lar, with biitoneislot or opening 'r, as in Figs.

1 and 2, I may form the guidesurface as shown in Figs. 5 and 6, wherein are employed three disks, 8, pivoted at t, the peripheries of the disks bearing-against the top ,piece or upper 'end eitens'i'on'of the'b'obbin,"forming a guiding-surface or wall, with three bearing points between it and :the top piece, and there are spaces at each side of each bearing-point.

In this modification it is not actually necessaryto groove or notch the top piece, as shown in'Fi'g.3, andit may be left plain,.for

the disks turn with the top piece, and .the

yarn, contained in one of the spaces between the rollers and toppieee, when the bobbin acts to wind the yarn, slips andis'move'd'from one -space to theoth'erbetween rotating surfaces, injurious rubbing friction between the top piece andguidewall or surface beingth'ereby avoided, atthe same tim'e'that a true bearing-surface for the top piece is preserved.

The yarn passingfrom 'thefront rolls to the spacesabove described, passes also through a guide-wire of usual construction.

In Fig.7 the guide-opening is made in "a 'blok,but instead of being circular, it is-provid'ed with spaces 12, for the reception and passage of yarn,'the spindle then being preferabiy'plain. I do not broadly claim a'hinged or movable guide-board providedwith a'bearing'for the'upper end of the bobbin,'norsuch a guideboard with a guide-wire.

'1 claim '1. 'A whirl, and a bobbin adapted to be moved by the whirl, iircombination with a top-piece and a guide-surface therefor, the top piece "and guid'e-surface being constructed withproje'ctin'g bearing-points and intervening spaces for the yarn, to'steady the bobbin and to permit the yarn to slip from one to 'theothe'r' spacewhen the yarn is being wound upon the bobbin, substantially as described.

-2. In combination, a bobbin-and a top piece, and a guide surface'or wall constructed to atford projecting bearing-surfaces and "spaces at intervals, as described, and having 'a 'slot "leading'to such spaces, substantially 'asile- "scribed.

In testimony whereof have 'si'gn'ed" my name to' this specification in the-presence of two subscribing witnesses.
